I have 3 engine codes on my Silverado..?
I have a 1999 5 speed manual lifted silverado with:
P0171 - fuel trim system lean bank 1
P0300 - engine misfire detected
p0449 - evaporative emission vent solenoid control circuit
Will any of these codes be an expensive fix? I don't know much about any of them, if someone that knows could please help me out.

Fix the P0449, that should take care of the vacuum issue and lean misfire that's caused the others.
the solenoid is on the driver side frame rail behind the cab ...remove it and blow it out with compressed air usually unsticks it...if you haven't broken it or the wiring to it...
